I know here in Ontario that you're on probation for the first 3 months and your employer doesn't need to justify a reason to dismiss you. So I really don't think a 'reference mill' or a 'diploma mill' would even be capable of working here as you can hire anyone who sounds good and if they turn out to be crappy, you can just fire them.

I don't really see this as being useful unless you're already talented. IE my brother is a great programmer and has been asked to speak at conferences, but because he never got a degree he has no hope at certain companies, which IMO is absolutely moronic.
